Photographer's Note

A wonderful thing about African kids is their interest in posing in front of a camara. Many of them are actually aware nowadays about digital photography, and what they ask as a retribution is to see the image of themself on the cameras mini screen, then a big smile is produced. I wish I could have a portable printer with me and give them a paper copy after taking the shot. Does anybody know about a mini portable printer, ideal for field purposes?
